....repeated use and explicit referencing, are possible to record in physical systems, although even then it may be exorbitantly expensive. Most, such as examining, considering or querying are not. They can however be captured by transaction logging systems (e.g. Borgman, Hirsh and Hiller, 1996; Flaherty, 1993]) 8 Type of Usage Data Example Purchase buys book Assess evaluates or recommends Repeated Use multiple check out stamps Refer cites or otherwise refers to document Mark Add to a marked or interesting list Examine looks at whole document Consider looks at abstract Glimpse sees title ....

....are not tagged by language) These issues remain to be incorporated into our digital library architecture. 5. 4 Graffitti Various examinations of public access retrieval systems have noted small numbers of graffiti queriesterms, sentences, or even paragraphs of obscene or irrelevant entries [10]. When scanning the lists of query terms, we noted a few examples in the CSTR transaction logs. Some graffiti, particularly the bursts of expletives, may have been entered to vent frustration at the system or at search results. Or perhaps some users were curious as to whether various naughty words ....

....of implicit data does not pose difficult technological problems: many information access tools could easily be modified to record most of the categories of data in Table 1. In addition, there is a considerable body of research in LIS on the closely related field of transaction log analysis, e.g. (Flaherty, 1993). Data acquired through transaction log analysis has been passed back to designers to refine their systems (typically through user interface modifications) In contrast, an implicit rating system directly accesses the data to modify the system there is no human in the feedback loop. Implicit ....
